How to launch a corporate merch line in Mexico — 90-day roadmap

The 7 milestones of the 90-day roadmap

1. Days 1–15: catalog definition. Decide the 4–12 pieces that will make up the line, based on three axes: brand identity (which pieces reflect the brand best), utility (which pieces the customer uses in their day-to-day) and production viability (what can be manufactured in Mexico with consistent quality). Document in a spec sheet per SKU with dimensions, materials, decoration technique, weight, target cost and retail price.
2. Days 15–30: pricing and costing. Calculate the product cost (material + labor + decoration + packaging), the logistics cost (storage + shipping + returns), the channel cost (marketplace commission or distributor margin) and the target margin (typically 35–55% on product cost). Define the retail price in Mexican pesos before VAT and compare against the alternative of importing the same product from Asia under IMMEX.
3. Days 30–45: supplier selection and first prototype. Contact 2–3 workshops per category, request a quote based on first batch volume (typically 300–1,000 units per SKU), ask for a physical prototype before closing with the supplier and validate color, materials and decoration technique against the original brief.
4. Days 45–60: packaging and labeling. Design primary packaging (bag, box, sleeve), secondary packaging (shipping box) and labeling per NOM-050 (fiber composition, country of origin, care instructions) and LFPCOR (consumer information). Packaging is the brand's first impression in the customer's hand.
5. Days 60–75: first production batch. Issue the PO to the selected supplier, deposit 50%, supervise production with an in-person visit or video call and approve the strike-off before the full run. Typical timeline: 18–28 business days for national production, 35–55 business days for production with imported components.
6. Days 75–85: launch in chosen channel. Publish on MercadoLibre Mexico with full shipping, on Amazon Mexico with FBA logistics, on own Shopify with Stripe or Mercado Pago gateway, or on B2B channel with direct quote. Upload professional photos (at least 5 per product), description with SEO keywords, technical specifications, size chart where applicable.
7. Days 85–90: measurement and adjustment. Analyze first sales, returns, comments, customer acquisition cost, repurchase rate. Adjust catalog (drop what does not rotate, repeat what does), pricing (raise or lower based on elasticity), channel (move budget to the one that converts better).

Common errors that kill the line before it starts

The first error is launching 20 SKUs. Catalog dispersion kills learning: nobody learns what rotates if there are 20 distinct products. An initial line of 4–8 SKUs allows focus, repeat ordering and pricing learning without dispersing working capital.

The second error is underestimating packaging cost. A nice box costs between MXN 18 and MXN 65 per unit; a sleeve with seal costs between MXN 6 and MXN 14; NOM-050-compliant labeling costs between MXN 4 and MXN 9. Added to product cost, packaging can represent 15–25% of total cost.

The third error is choosing channel before catalog. MercadoLibre, Amazon, own Shopify and direct B2B have different audiences, commissions and margins. The catalog adapts to the primary channel (MercadoLibre wants aggressive retail price, B2B wants corporate packaging, own Shopify wants storytelling), not the other way around.

The fourth error is skipping the prototype. Buying 1,000 pieces without a physical prototype leads to delivering 1,000 pieces with the wrong logo, the miscalibrated color tone or the off-size measurement. An MXN 800–2,500 prototype saves a lost batch of MXN 80,000–250,000.

The fifth error is not calculating working capital. A line with 8 SKUs, 500 units per SKU, average cost of MXN 150 per unit, requires MXN 600,000 in inventory alone before the first sale. Without that cash, the launch stalls at the third order.
